The Application Layer : Process-to-Process Communication
During this tutorial, we have gone through the first four layers of the OSI Model and discussed each of them separately in a dedicated chapter. Now, in this chapter, we […]
The Transport Layer : End-to-End Communication
By now you should know that machines connected to the same network rely on the data link layer in order for them to talk to each other. And if two […]
The Network Layer : Connecting Networks
In the last chapter, we learned how we can connect computers to a network and make them talk to each other. Now, what if we want to talk to a […]
The Data Link Layer : Communication within a LAN
In the last chapter, we have learned that layer 1 is responsible for the physical transmission of data between connected machines. The physical layer receives that data from the layer […]
The Physical Layer : How Machines Are Connected
Now that we have learned about the layers that make up the OSI model, let’s go ahead and discuss each of them separately. In this chapter, we’ll learn about the […]
Introduction to the OSI Model
In order to understand computer networks and how they work, we first need to learn about the OSI Model. The OSI Model is a standard that defines a set of […]
